“…Hallux valgus (or bunion) is one of the most prevalent musculoskeletal problems affecting 23% of the adults and 35.7% of the elderly population ( Nix et al, 2010 ). It reduces the quality of life, impairs balance and gait, and increases falling risks ( Munteanu et al, 2017 ). Genetic and sex dimorphisms are the intrinsic causes and undoubtedly predisposes general laxity and hypermobility that plays a major role in driving the development of hallux valgus ( Mansur and de Souza Nery, 2020 ).…”

Hallux valgus is a common foot problem affecting nearly one in every four adults. Generalized ligament laxity was proposed as the intrinsic cause or risk factor toward the development of the deformity which was difficult to be investigated by cohort clinical trials. Herein, we aimed to evaluate the isolated influence of generalized ligament laxity on the deterioration using computer simulation (finite element analysis). We reconstructed a computational foot model from a mild hallux valgus participant and conducted a gait analysis to drive the simulation of walking. Through parametric analysis, the stiffness of the ligaments was impoverished at different degrees to resemble different levels of generalized ligament laxity. Our simulation study reported that generalized ligament laxity deteriorated hallux valgus by impairing the loadbearing capacity of the first metatarsal, inducing higher deforming force, moment and malalignment at the first metatarsophalangeal joint. Besides, the deforming moment formed a deteriorating vicious cycle between hallux valgus and forefoot abduction and may result in secondary foot problems, such as flatfoot. However, the metatarsocuneiform joint did not show a worsening trend possibly due to the overriding forefoot abduction. Controlling the deforming load shall be prioritized over the correction of angles to mitigate deterioration or recurrence after surgery.

“…By comparison, modern lifestyles and habitats are a blink of an evolutionary eye to which our species is yet to phylogenically adapt, but to which we do ontogenically adapt ( Figure 1a and Figure 1b). Deformations of foot structure and subsequent impaired foot function are examples of ontengenic adaptation known to relate to years of narrow footwear use [11,12]. A mismatch between what humans are adapted for and the habitat in which we now exist is suggested to underpin many health and injury problems [10,13].…”

“…There is a dearth of longitudinal studies examining the effects of long-term shoe wear on foot function. However, a recent prospective, long-term follow up, study using large samples of mono and dizygotic twins provided strong evidence that development of great toe deformity (hallux valgus) is not genetic, but is significantly associated with years of wearing narrow shoes, with frequent use increasing risk of developing toe deformity by almost three fold [11].…”

ance-running specialists [1-3]. However, injury rates ranging from 20-79% [4-6] suggest modern humans are prone to injury in running which the Endurance-Running hypothesis contends is a species-specific movement pattern for which we are well adapted. Explanations and solutions focus largely on shoe design and gait mechanics. Foot structure and function, in contrast, have received little attention in running-related research [7]. Moreover, and despite continued interest in running-shoe design, there has been little attention on how footwear might influence foot structure and function and therefore the rest of the kinetic chain above it. This opinion piece addresses these issues and proposes a novel perspective that could add to factors explaining injury risk in endurance running. Endurance-Running Hypothesis The fossil record of the genus homo shows evidence of musculoskeletal adaptations that reduce the mechanical and energetic demands of bipedal-endurance running. Adaptations differentiating homo sapiens from early homo and from primate ancestors include the nuchal ligament for head stabilisation, a mobile thoracic spine permitting counter rotation of the trunk and legs, long legs that lengthen the stride so reducing energy cost per unit of distance, large proximal hip muscles (gluteals) to control forward pitch of the torso at ground contact, long Achilles tendons and plantar arches to facilitate energy storage and return, and short-straight toes that minimise toe flexion moments and smooth the forward trajectory of body weight over the supporting foot [1-3]. Many of these adaptations benefit running only, suggesting that
